On the other hand, in graph-based quantum gravity states, such as in
Loop Quantum Gravity [1]}, Causets [2]} or Quantum Graphity [3]}, spacetimes which are not macrolocal are very natural, and violation of macrolocality appears in the form of non-local links.
A first study of the physics of these non-local links was carried out in [4]}, [5]}.
